These COTS antennas are designed for small satellite applications to realize satellite communication links. Their mechanical dimensions fit CubeSats as well aslarger satellites. Various designs of different frequencies are available, and customized solutions can be provided.
With circular polarization, the antennas provide a robust solution regarding the steering accuracy to
the ground station antenna. Due to up to 16 combined patches, a high antenna gain can be achieved while meeting small form factor requirements.
A robust SMA (female) connector is used as the RF interface. Suitable screws ensure proper mounting of the antenna. The antenna backside shall be grounded properly to the satellite chassis. ROGERS laminate for space applications is used as dielectric. The patches and conductors are copper with gold surface finish.
The basic design has achieved TRL 9 with various successful LEO missions. Alternative designs for X- Band uplink frequency and X-Band downlink frequency are available.
